Through Hole Resistors are commonly used components in electrical and electronic circuits. They are used to limit current, and to adjust signal levels, among other applications. The most common type of Through Hole Resistor is the 81F1R82, which consists of two resistor elements in series, enclosed in an epoxy package. This article will discuss the different applications and working principles of the 81F1R82.

The first application of the 81F1R82 is as a current limiter. When used in this way, the two series resistors can be used to decrease the amount of current flowing through the circuit. By increasing the two series resistor values, the overall resistance of the circuit is increased, and this in turn reduces the amount of current that can flow through the circuit. This type of current limitation can be used to protect other components that are more susceptible to damage due to excessive current.

The second application of the 81F1R82 is as a signal level adjuster. By connecting either of the two series resistors in series with other components in the circuit, it is possible to adjust the voltage level. This is useful for adjusting the signal level of an audio signal, or for adjusting the gain of an amplifier. By increasing the resistance of either of the two series resistors, the overall resistance of the circuit is increased and the signal level decreases. Conversely, by decreasing the resistance of either of the two series resistors, the overall resistance of the circuit is decreased and the signal level increases.

The 81F1R82 is also widely used as a voltage divider. As with the current limiter, the two series resistors can be used to decrease the amount of voltage in a circuit. By increasing the resistance of either of the two series resistors, the overall resistance of the circuit is increased, and this in turn lowers the voltage in the circuit. This is often used to adjust the input voltage for motor speed control, or for other voltage-sensitive components.

The 81F1R82 is also used as a voltage regulator. By placing a zener diode between the two series resistors, it is possible to incorporate a voltage regulator into the circuit. This is useful for circuits that require a very constant voltage level, such as those used in digital circuitry. The zener diode allows for some current to flow through the circuit even if the input voltage is above the regulated level. When the input voltage is below the regulated level, then virtually no current flows through the circuit.

The working principle of the 81F1R82 is relatively simple. The two series resistors act as a voltage divider, and the zener diode acts as a voltage regulator. When the voltage across the two series resistors is constant, the resistance is also constant and the current through the circuit is constant. When the input voltage is variable, the voltage across the two series resistors is also variable, and the resistance is automatically adjusted to maintain a constant current.

In conclusion, the 81F1R82 Through Hole Resistor is a versatile component that has a wide range of applications. It has the ability to limit current, adjust signal levels, and regulate voltage levels. With its simple working principle, it is an excellent choice for a wide variety of circuits. Therefore, the 81F1R82 Through Hole Resistor will continue to be a popular choice for many applications.
